Abstract: 1285260 Coating with nitrides or carbonitrides DEUTSCHE EDELSTAHLWERKE AG 18 Nov 1970 [28 Nov 1969] 54883/70 Heading C7F A body made from a metal carbide, e. g. W C and a metal binder, e. g. Fe, Co, Ni, Mo is coated with a nitride or carbonitride of one or more metals of Groups IVa to VIa of the Periodic Table. The coating may be deposited by heating the body to 800 to 1150 C. in an atmosphere of a halide, e.g. titanium tetrachloride, nitrogen, hydrogen and possibly a hydrocarbon e. g. methane. The reaction may take place while the body is embedded in a powder mixture of metal nitrides or carbonitrides. Metal chlorides which are solid at room temperature may be dissolved in titanium chloride. The body may be first rotated in the powder mixture to rub off the sinter skin.

Title: Circuit for Sequentially Energizing a Plurality of Loads
IPC: B60Q1/38
Filed: 1968-12-05
Abstract: 1,191,000. Signals on vehicles. GENERAL MOTORS CORP. 5 Dec., 1968 [8 Dec., 1967], No. 57749/68. Heading G4Q. [Also in Division H1] In a circuit for sequentially energizing a plurality of loads, such as turn signal lamps, having a relay with a pair of coils 62, 64 which can develop magnetic flux in opposition, a capacitor 96 is connected in series with one of the coils 64 so that the net flux developed by the coils varies from a minimum to a maximum over a predetermined time interval and armatures 82, 84 (Fig. 3), actuable in response to different levels of magnetic flux operate contacts 88, 92; 90, 94 to sequentially connect a source 10 to the loads 24, 26. In the turn signalling arrangement shown (Fig. 1) the turn switch 12 is in the neutral position. If brake pedal switch 56 is actuated rear lamps 22 and 28 light and the currents through relay coils 62, 62<SP>1</SP> cause the relay contacts 88, 92, 90, 94 and 901, 94<SP>1</SP>, 88<SP>1</SP>, 92<SP>1</SP> respectively to close to light lamps 24, 26, 30, 32 so that all the rear lamps are lit. To select a left-turn the movable contacts 50, 52 of the turn switch 12 are moved to the right to engage fixed contacts 38, 42 and 40, 44; 46, respectively. Front left turn signal lamp 18 and pilot light 34 are then energized via ignition switch 14 and a thermal flasher 16 and rear left turn signal lamp 22 is also energized directly via the turn switch 12. The relay coils 62, 64 act in opposition so that the net flux produced rises from a minimum to a maximum as capacitor 96 is charged. The armature 84 (Fig. 3) has a smaller biasing spring 78 than the spring 76 of armature 82 so that armature 84 is pulled to close contacts 90, 94 before armature 82 closes contacts 88, 92 such that the rear left signal lamps 22, 24, 26 are sequentially lit. If the brake switch 56 is closed whilst giving a left turn, the right rear signal lamps 28, 30, 32 are all lit. The flasher 16 is now heated sufficiently and opens the supply to the relay coils so that relay is de-energized and the lamps 24, 26 go out. Provided the turn switch 12 is still closed the above operation is repeated. The three lamps 22, 24, 26 must all become energized before the ON period of the flasher 16 ends. A diode and resistor 100, 102 provide a discharge path for the capacitor 96 so that delayed opening of the relay contacts is prevented. When the turn switch 12 is returned to the neutral position the contacts of the relay open and all the lamps go out. The operation for the right turn is similar to above. The relay coils may be bifilar wound. By using a flasher 16 capable of a four lamp load, e.g. 18, 22, 24, 26 (Fig. 2, not shown) instead of the three 18, 22, 26 of Fig. 1, the resistor 102 and diode 100 may be eliminated and the contact 94 is also fed from the flasher 16 via contact 40.

Abstract: 1354920 Converter construction GENERAL ELECTRIC CO 17 Dec 1971 [21 Dec 1970] 58640/71 Heading H2F [Also in Divisions H1 and F4] Fig. 5 shows a housing for a plurality of controlled- or diode-rectifiers. The rectifiers (20) and their local heat-dissipating structures form units 22 which are mounted on panels 21 which are used in pairs 35, 36, 37 together with insulating sections 47, 48 to define the walls of coolant channels in the housing. The cooling fluid (air) enters the housing through apertures 61, 62 and passes down channels 51, 57 which decrease progressively in cross-section to provide the same fluid pressure at pairs 35, 36, 37. This arrangement gives equal fluid flow through the (identical) pairs, the outlet channels 50, 54, 60 being increased progressively in cross-section to the same end. Preferably the pressure drop through each pair is considerably greater than that in the channels. The walls of the housing (not shown) in the plane of the drawing may have removable sections to allow the withdrawal for replacement of the rectifier panels along rails extending perpendicularly to the plane of the drawing. In suggested variants the pairs of panel are replaced by single or multiple panels. An individual insulating panel 21 may be of the form shown in Fig. 6 where the controlled rectifiers 20 are clamped under pressure between duct-forming electrode cooling bodies 23 and the units 22 thus formed are attached to the panel together with a saturable reactor 28, gate-pulseforming circuitry 27, and protective circuitry (not shown) for the rectifiers. The housing of Fig. 5 may contain one or more units comprising four paralleled strings of fifty SCRs. One or more of such housings may be mounted on the floor of a large closed building (Fig. 7, not shown) in a room (74) which effectively acts as an infinite air source, the air leaving the exit channels being drawn through an underfloor plenum chamber (75) by a battery of fans (76) and being returned to the room (74) through an air/glycol heat exchanger. A use for the housed controlled rectifiers is in the provision of the bridges 141-146 and 141'-146<SP>1</SP> used in one terminal of an HVDC link (Fig. 1, not shown). A.C. fed to phase terminals ABC is taken to the two bridges in one case by a double star transformer 12 and in the other case by a delta-star transformer 13 to provide a 30 degree lag to the second bridge. The outputs of the two bridges are connected in series. The rectifiers of each bridge are fired in their numbered sequence at 60 degree intervals. When the firing angle is zero the average rectified D.C. output is at its maximum; as the firing angle approaches 90 degrees the output falls to zero. The transfer direction of the link may be reversed by using a firing angle of over 90 degrees so that D.C. fed to terminals de<SP>1</SP> (with d negative) provides A.C. at terminals ABC.

Abstract: 1418658 Rotary positive-displacement pumps A A SCHMITZ 28 Dec 1972 59917/72 Heading F1F A vane-type pump wherein the flow is variable by means of a cam ring 83 which is slidable in a housing 4, includes sealing zones 113, 114 on the cam ring between the inlet and outlet zones 107, 108, which sealing zones, in all positions of the ring 83 relative to the rotor, are formed so as to have a radius from the rotor axis which does not increase in the direction of rotor rotation. As shown, the radius decreases. The vanes are constructed so as to be fluid-pressure balanced radially Fig. 3 (not shown) with the result that only centrifugal forces act on the vanes and thus the decreasing radius of ring 83 at the sealing zones forces the vanes inwardly and thus maintains contact between the vanes and cam ring. Otherwise, the pressure differential across each vane in the sealing zones would cause the vanes to be thrust against their slots with possible resultant frictional jamming.
